Using Those 100k+ United MileagePlus Miles

As we’ve mentioned, you have plenty of redemption options with MileagePlus. Here are 3 ideas to think about:

Fly First Class on Thai Airways: Travel to Asia on Thai Airways in luxury. A first class ticket from the U.S. is 130,000 United miles. Plus, enjoy access to the Thai Airways First Class Lounge!

Because Thai Airways does not fly directly to the U.S., you’ll have to fly with a Star Alliance partner and connect through Europe.

Travel to Africa in Business Class: Want to visit Africa? Redeem 80,000 United MileagePlus miles to fly on a Star Alliance carrier to Africa from the U.S. 

Take Lufthansa First Class: Redeem 110,000 miles and fly in style on a one-way first class ticket from the U.S. on Lufthansa. Connecting through Frankfurt allows you to visit the First Class Terminal, known for its absolutely fabulous airport lounge. You can even take a bath while you wait for your flight!!


By now, we hope it’s clear how easily you can earn 100k+ United MileagePlus miles in a very short time. For more strategies, read our guide to earning miles, which includes loads of examples you can learn from.
